IMG

Display slices of a 3D object, frame by frame using GUI controls

Displays single/multiple images with given titles. See examples for more details
******************** Quick Description ********************
ob: can be a 2D/3D numerica array or 1D cell with each cell as a 2D numeric matrix
label: empty [] OR string OR a 1D cell same length as the z direction of *ob*
******************** GUI instructions ********************
'd' OR 'right arrow': next image
'a' OR 'left arrow': previous image
'w' OR 'up arrow': first image
's' OR 'down arrow': last image
'c': close figure
******************** Examples: main ********************
img(ob1);
*****ob1: 2D/3D array
img(ob1, label1);
*****ob1: 2D/3D array
*****label1:
**********empty [] (if array is 3D, then title of each 2D frame will be 'frame: 1', 'frame: 2',...) OR
**********1D cell (each cell corresponding to each 2D frames) OR
**********a string (for all 2D frames)

img(ob1, label1, ob2, label2, ...);
*****ob1, ob2, ... have the same size in 3rd dimension (size(ob,3))

******************** Examples: modes ********************
img(___, 'size', [1,3]);
*****generates subplot(1,3,kk)

img(___, 'axes', 'off');
*****remove white space between axes

img(___, 'auto-pos', 'on');
*****sets the figure position so that the mode ('axes','off') actually removes all white space.
*****only works if 'axes' mode is at 'off'

img(___, 'abs', 'on');
*****only plot absolute values of given pixel value
*****set to 'off' if wishes to plot actual real values (negative and positive)

img(___, 'colormap', 'jet');
*****uses the colormap 'jet'
*****can be changed to any MATLAB colormap

******************** Remarks ********************
If label is a string, then DO NOT USE mode names, e.g., 'size','axes', etc.
